Section 779.15(a) Continued. <br />r~ <br />Revised 11/20/80 <br />Data gathered with respect to the Michigan River alluvium can be <br />directly correlated to prevailing conditions in the Illinois Rivez <br />alluvium. From the conclusions drawn by the USGS from their recon- <br />naisance studies, and from observations of the similarity in the <br />geomorphology of the alluvial deposits of the <br />Illinois and Michigan Rivers shown on Map Sa, North Park Hydrology, <br />the data given above are used to quantify the characteristics of <br />the alluvial aquifer in the tipple area. <br />The water quality of the alluvial aquifer in the tipple area is <br />based on samples taken from the marsh surrounding the tipple and <br />analyzed for major and trace constituents. These analyses are <br />listed in Table 10, Kerr Tipple Area Water Quality Data, and sample <br />sites are shown on Map 17a, Kerr Tipple Area Hydrology. These data <br />document the conclusion that water quality in the tipple area is <br />• suitable for domestic or agricultural use, and that water quality <br />limitations for dissolved constituents set by the U.S. Public <br />Health Service are not exceeded, in either baseline or affected <br />waters in the tipple area. <br />(Return to page 779-38, Section 779.16 Surface Water Information) <br /> <br />779-38 as <br />
